1. A power control system for controlling the transmission energy of signals from a remote transmitter, comprising:
- closed loop power control means for generating closed loop power control commands in accordance with a comparison between a first received signal quality metric and a variable threshold;
an outer loop power control means for determining said variable threshold in accordance with a second received signal quality metric; and
detector means for suspending the operation of said outer loop control means in accordance with a determination that said remote transmitter is not responding to said power control commands in a predetermined fashion.

Abstract
A power control system for controlling the transmission power in a system wherein the transmission power may be gated or capped. The receiver employs a combination of closed loop and outer loop power control. The outer loop is frozen upon detection by the receiver that the signal has been capped or gated.
